OGUK Pathway to a Net-Zero Basin: Production Emissions Targets Report 2020

ii. Localised CCS The use of CCS on individual assets to capture CO 2 from power turbine or compressor exhausts could incorporate sequestration of CO 2 into a reservoir for storage and/ or enhanced oil recovery (EOR) or transportation to shore of captured CO 2 for processing and then offshore sequestration. Development of localised CCS is most likely to be viable when part of a larger CCS project iii. Offshore integrated energy hubs The future development of offshore hubs (in which a number of interconnected offshore platforms share a centralised renewable power supply) perhaps producing hydrocarbons or hydrogen and/or storing CO 2 in offshore reservoirs could be used to realise a step-change in emission reduction fromupstreamoil and gas operations and to lay the foundations for large scale emissions capture for the wider UK economy.

iv. Increased use of electrical power at onshore terminals and processing plants Most onshore terminals are connected to the national grid, and some or all of their power is supplied from grid electricity. Fuel gas and other hydrocarbons are often used for generating process heat and compression because they are currently more efficient than electrical heating alternatives. Step-change actions to reduce emissions at these terminals could include increased use of electrical power, re-sizing to reduce the number of compressor trains and consolidation of processing to increase efficiency by maximising throughput. Alternative approaches to process heat generation include harnessing waste heat from other processes such as hydrogen production. Research is ongoing on the opportunities to reduce emissions in the exploration, logistics, decommissioning and aviation sectors. Solutions could include increased used of electrical power and batteries and the use of alternative fuels such as ammonia or hydrogen.
